Ukrainian Catholic, considering orthodoxy
"Take not of those who hold heterodox opinions on the grace of Jesus Christ which has come to us, and see how contrary their opinions are to the mind of god... They abstain from the Eucharist and from prayers because they do not confess the Eucharist is the flesh of our Savior Jesus Christ, flesh which suffered for our sins and which that Father, in his goodness, raised up again. They who deny the gift of god are perishing in their disputes"
- St. Ignatius of Antioch, 110 AD
